Software Requirements Specification Data Item Description (SRS DID)

3.1 The Software Requirements Specification (SRS) specifies the requirements for a Computer Software Configuration Item (CSCI) and the methods to be used to ensure that each requirement has been met. Requirements pertaining to the CSCI's external interfaces may be presented in the SRS or in one or more Interface Requirements Specifications (IRSs) (DI-IPSC-81434) referenced from the SRS. 3.2 The SRS, possibly supplemented by IRSs, is used as the basis for design and qualification testing of a CSCI. 7.1 This Data Item Description (DID) contains the format and content preparation instructions for the data product generated by specific and discrete task requirements as delineated in the contract. 7.2 This DID is used when the developer is tasked to define and record the software requirements to be met by a CSCI. 7.3 Requirements pertaining to CSCI interfaces may be presented in the SRS or in IRSs. 7.4 The Contract Data Requirements List (CDRL) (DD 1423) should specify whether deliverable data are to be delivered on paper or electronic media; are to be in a given electronic form (such as ASCII, CALS, or compatible with a specified word processor or other support software); may be delivered in developer format rather than in the format specified herein; and may reside in a computer-aided software engineering (CASE) or other automated tool rather than in the form of a traditional document. 7.5 This DID supersedes DI-MCCR-80025A and DI-MCCR-80301.
